超声心动图对新生儿持续肺动脉高压的诊断价值分析

Analysis of echocardiography in diagnosis valuation of persistent pulmonary hypertension in newborns

目的分析超声心动图对新生儿持续肺动脉高压的诊断价值。方法 64例患儿经超声心动图检查诊断肺动脉高压,除动脉导管未闭与卵圆孔未闭外,不伴有其他心脏结构异常;按照尖瓣返流压差法估测肺动脉压力,并分为轻、中、重度三组。结果随肺动脉压力上升,患儿心脏右心各腔室有增大趋势;所测肺动脉压力变化与患儿临床表现及疗效相一致。结论超声心动图是新生儿持续肺动脉高压有效的无创诊断方法,不仅可用于临床确诊,还对病情判断、疗效观察以及预后评估具有重要价值。

Objective To investigate the value of echocardiography in the diagnosis of persistent pulmonary hypertension in newborns. Methods Totally 64 children diagnosed by echocardiography pulmonary hypertension,in addition to patent ductus arteriosus and patent foramen ovale,but not associated with other cardiac structural abnormalities,accordance with mitral regurgitation pressure method to estimate pulmonary artery pressure,and were divided into mild,moderate and severe three groups. Results There was direct correlation between degree of pulmonary hypertension and size of right ventricle,and the changes in pulmonary artery pressure were consistent with their clinical manifestations. Conclusion Echocardiography is persistent pulmonary hypertension of the newborn and effective non-invasive diagnostic method,not only can be used for clinical diagnosis,but also to determine the disease,efficacy and prognosis of great value.
